Hi GHL,

I have purchased a new Teco TR20 Chiller and here is my Question,

I have a Pro II EX and Temp probe is showing 27.3 deg but when I turned on the Chiller it is reading 24.5 deg. Now I know that the GHL is correct as I have checked using a Standard Thermometer. Just goes how accurate the GHL is.

My question is what settings should be used as it has be stumped.

My desiered temp is 26 deg.

I have it pluged into a digi Power Bar and this has been set to Temp 1 and chiller is selected. What temp di I set the chiller to and also what/how does the Hysterious work in this suituation.

Thankyou
